sparc: delete personality 1

sparc: delete personality 1

Personality 1 for sparc and sparc64 appears to be an old attempt
to support stracing Solaris binaries.

It stalled after the only syscall, solaris_open, was covered:
all other solaris_foo's are printargs.

This change deletes personality 1. Now sparc is an one-personality
arch, and sparc64 is a two-personality one.

For clarity, pure renaming of personality 2 files to personality 1 for sparc64
is performed in the next commit - this prevents a state where syscallent1.h
seems to indergo a lot of changes, where in fact in is deleted, and then
replaced by syscallent2.h

Therefore, tree at this commit will not build.
